View Full Version : Gamebit not fitting?

03-03-2003, 02:46 PM
I dunno if anyone else has had this issue, but I'll go ahead.

I got the gamebit head in the mail today from Vader (thanx man!) so I decided to try it out in the screwdriver set I got (has 2 dozen heads). Problem was, it didn't fit!

It fit in the screwdriver no problem but didn't fit in the hole where the gamebit screw is on a NES cart (I know Tengen carts require different bits I've noticed). Anyone else experience this?

There is a different bit for carts and systems.

Little off topic, but is there a bit that can get those deeply imbedded Virtual Boy screws?

The bit I got from Vader is a 3.8mm gamebit. He said it was the security bit to open up NES carts with.

I got a bit like that late last year. Mine didn't fit quite right in the cartridge shell either. It was a little bit too wide.

BUT, as none of my carts were particularly rare/valuable, and I don't really collect NES stuff very much, I went ahead and shoved the bit in anyway. It is still usable, it just shaves the hole in the plastic out a tiny bit. Aside from the plastic dust the initial unscrewing generates, it's no problem.

Is this usual of security/gamebits?

There are two "brands" in my experience. The standalone bits you buy seem to be prone to this size problem. I got a pair of gamebits that were part of an entire sucurity bit/driver set from Sylentwulf. The gamebits in that set were way better, and fit into carts like butter.

It seems YMMV with these bits.

I have the stand-alone bits and didn't really notice a problem, save for like one or two carts. After a few uses though I noticed they fit in the screw holes in general better, though.

I bought the stand along version from MCM years ago and I haven't had any problem fitting either. Maybe something changed during the production?

And I'd like to know about the deep screw hole in the VB cuz one of my VB's left eye isn't working at all.

Just got your message, does it seem to be too big or too small?? Let me know, I will try and help you out.

Too big it seems.

pm me with your address again

Where you get these bits anyhow?

What other sizes are there that will actually fit in a NES cart?

MCM electronics. I have an account with them, I can just return the bit if it is defective.

What other sizes they come in?

3.8mm and 4.5mm (for SNES consoles)

If the bits are just a little too big, you could use a bench grinder to grind a bit off. That's what I had to do to my screwdriver when it wouldn't fit in SNES console holes on the back.

03-04-2003, 01:33 PM
The bit Vader sent me was the 3.8mm bit.

Just saw this post. Quick note, the bits fit in a LOT of NES carts VERY tightly, no matter what bit you buy. It's not that the bit is too big, the problem is that it's EXACTLY the right size, so you do have to twist it in and kinda force it in there sometimes. Haven't ever really damaged a cart this way, but no guranatees on that since I haven't opened a hwole lot of NES carts either :)

Not that I've found or heard of... the way I do it is use a flathead screwdriver with a notch in it, check out the Disecting the Virtual Boy section on my page @ http://projectvb.vze.com .

ot a gamebit from Achika a while ago and it fits great , before that i was using the notched out flatblade screwdriver and a pair of electronic needle nose pliers

03-25-2003, 08:55 AM
Mine is always a fight fit but it does not damage the cart at all.

03-25-2003, 06:59 PM
mine fits in but it causes the white dust on the initial unscrewing that was mentioned earlier, it doesn't damage the cart though.

With mine (bought mine on EBay a while ago) it varies with each cartridge. Somtimes the bit goes in easy with some cartridges, other times it shaves off a bit of plastic on others.

If the bit feels a bit tight and it looks like you're going to be forcing the bit into the screw hole, try coating the bit with a dab of dish soap. It's helped me on some of my problem carts. It may still be a tight fit, but the soap prevents the bit from rubbing plastic off. Then after you reassemble the cart, just rub any excess soap out with a dry or lightly dampened cotton swab.

This trick also works on screws when trying to drill them into dense wood.

Yohi, that was the issue I was having- some carts it'd hit nicely, others would take some slight shavings off the plastic. Fits perfectly in my tengen carts.
